Even if the Google manifesto writer were correct about all of his suppositions, that implies that tech would still be 40-45% women, instead of less than 20%.
Though all of his points weren’t as prima facie absurd as made out to be (though some were indeed huge fails), I think tech would be better for the world and for humanity if it were about 70% women — not due to any biological differences but because women are socialized to be more well-rounded people than most men.
More well-rounded people == better outcomes.
Also, at the least women wouldn’t insist on making only huge phones no one smaller than 6’2″ can hold in their hand. That is a pet peeve of mine.
